So, if we all (US States/Provinces) fired down the coal plants - using them proportionally to the lack of sun and wind; and used solar, wind, and nuke power when they are available...
Not sure exactly what you are asking, but unfortunately the easiest systems to power up/down are the clean systems. You can shut off dams, windmills, and solar panels and the water/wind/sun keeps running, but without providing power. If you shut off a coal plant, the coal still burns.
IOW, simply flipping a switch will only shut off the turbines, not what powers it. In the case of the first three, a switch flip is all that is needed. In the case of coal, you have to shut off the really really really hot fire and then later start a fire and make it really really really hot.
Now, that doesn't mean that you can't replace those plants with better technology. It just means when you are looking at peak vs down loads, its the others that will be turned on and off. Coal will always be on.
.....more or less.......feel free to let an expert chime in.
